BODY=BOLS TER FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 693,160, dated February 11, 1902. Application filed September 30, 1901. Serial No. 77,092. (No model.)

To all whom it may concern:

Be it known that I, MoRsE B. ScHAFFER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Body-Bolsters'for Railway-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to body-bolsters for railway-cars; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed. I

The object of thisinvention is to provide a body-bolster for railway-cars consisting of a casting which is in trough shape and the sides of which curve outwardly throughout their height and form horizontal flanges at their upper edges,thereby forming a stronger bodybolsterlthau if the sides were flat and the flanges extended therefrom at a right angle.

Figure 1 is a side elevation of the complete bolster. Fig. 2 is a plan view. Fig. 3 is a longitudinal section. Fig. 4 is a bottom View of the bolster. Fig. 5 is a cross-section taken through the middle of the bolster. Fig. 6 is an end view with a part shown in section.

The bolster consists of the bottom 1, which extends upwardly in both directions from the center, where said bottom is extended downwardly, forming the center bearing 2. The bottom 1 is also bent downwardly to form the side bearings The sides 4, as clearly shown in Fig. 5, extend upwardly with outward curves, thereby forming a continuous curve from their lower to their upper edges. The said sides are extended horizontally at their upper edges, forming the flanges 5, through which are formed the bolt-holes 6. As above stated and as clearly shown in Fig. 5, the under sides ofv the flanges 5 are curved, and around the bolt-holes 6 are formed integral projecting ledges 7, which are to provide flat bearing-surfaces to receive the heads or the nuts of the bolts.

Integral with the outer side of the bolster are formed two projecting flanges 8, between which the draft-sills are to be secured and which are provided with openings 9 for. the reception of the fastening devices whereby the draft-sills can be held in place. The flanges 5 at the ends of the body-bolster are strengthened by the webs 10, connecting them with the ends of the bolster and serving as braces, whereby they will be more rigidly held in place.

king-bolt, and a corresponding opening 14 is formed through the web 11.

As it will clearly be seen by referring to Fig. 5, the sides 4 are curved throughout their width, and therefore I have provided integral lugs or ledges 15 to provide flat bearing-surfaces for the under side of the car-sills.- These ledges surround the openings 6 and correspond to the ledges 7, which are on the under sides of the curved sides 4:, to form flat bearing-surfaces for the bolt heads or nuts. These curved sides are for the purpose of providing equal expansion and contraction in the cooling of the metal of the casting, thus making a stronger bolster capable of carrying more weight and less liable to break undersevere strains and jars than a bolster having angular sides.

I claim- 1. A cast car-bolster having its walls curved for the purpose of avoiding undue strains in casting the bolster.

2. A body-bolster for railway-cars, consisting of a bottom and sides which are curved outwardly and the upper edges are provided with openings to receive bolts, ledges formed integral with the under side of said curved extensions to provide flat bearing-surfaces for the bolt heads or nuts, an integral web connecting the sides of the bolster at the center, braces 12 connecting said webs with the sides within the bolster, projecting flanges 8 integral with the outer side of the bolster and adapted to be attached to the draft members, and center and side bearings formed on the under side of the bolster, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

MORSE B. SOHAFFER.
